Hydro One confirms details of early morning power "blip"

TORONTO, Jan. 30 /CNW/ - On Tuesday, January 30th at 6:22 a.m., Hydro One
experienced an equipment failure at its Richview Transformer Station. A
capacitor bank which was coming online to increase voltage to respond to
demand during the early morning peak failed causing a momentary drop in
voltage or "blip in power". The faulted equipment was isolated immediately and
removed from service.
Hydro One estimates the blip lasted less than 1/5 of a second.
Both residential and industrial customers may have been affected by the
blip. Electronic systems sensitive to voltage fluctuations may have been
affected.
The failure of the capacitor bank resulted in a fire at Hydro One's
Richview Station. Hydro One personnel were on scene at the time of the
incident and followed established emergency and safety procedures and
contacted local fire officials. Emergency crews extinguished the fire by
7:30 a.m.. Local police, also on scene, have ruled out criminal activity.
There has been no additional impact to the power supply system as a
result of this morning's incident. The cause of the equipment failure is under
investigation.
